It can be de-iced by hot fluoride defrosting.
To de-icing, first disconnect the power supply of the refrigerator and take out the food in the box. Then, depending on the size of the freezer, one or two aluminum lunch boxes are filled with boiling water and placed in the freezer. After a few minutes, the frost on the freezer wall begins to fall off in its entirety (for those that have not yet come off, you can gently wrench it by hand).
If there is no metal evaporation plate on the top of the freezer, the lunch box with boiling water should be covered to avoid deformation of the plastic inner wall at low temperature due to sudden heating. This method saves much less time than a power outage that heats up on its own. Be careful not to hit the frost layer with a wooden rod or metal device to prevent unnecessary trouble caused by accidentally hitting the ring evaporator.
What causes the freeze in the refrigerator
Usually when using the refrigerator, if the hot food is directly placed in the refrigerator, it is easy to lead to an increase in the moisture inside the refrigerator, and when the temperature drops, the increased moisture will condense on the inner wall of the refrigerator because of the decrease in temperature. At the same time, when some foods with more moisture content are placed in the refrigerator, the additional moisture generated by the food will increase the technical area of the refrigerator, which is also easy to cause the refrigerator to freeze.
